Normal Distribution

The well known bell shaped curve. According to the Central Limit Theorem, the probability density function of a large number of independent, identically distributed random numbers will approach the normal distribution. In the fractal family of distributions, the normal distribution only exists when alpha equals 2, or the Hurst exponent equals 0.50. Thus, the normal distribution is a special case which in time series analysis is quite rare. See: Alpha, Central Limit Theorem, Fractal Distribution.

Bell Curve

A curve on a chart in which most data points cluster around the median and become less frequent the farther they fall to either side of the median. When plotted on a chart, a bell curve looks roughly like a bell.

The distribution of these CVs for popping expansion was close to the normality, and the shape of this Gaussian curve was classified as platykurtic because of its flattered curvature (FERREIRA, 2005).
When a single Gaussian curve is expressed with the following formula:
Analysis with the GcTm algorithm of the dissociation data gave Tms with higher resolutions than those reported by the SDS software, based on a gaussian curve fitted to multiple data points (on average 5.
The Gaussian curve can be considered as the intensity distribution expected for binder surface reflections, without any contribution from pigment particles or pits.
